A security alarm is simply a system made for detection of intrusion, including unauthorized entry into a structure or other enclosed areas like a house or a school. Security alarm manufacturers usually sell alarms that can be installed on doors and windows of the facility, as well as at various points in the facility itself. The alarms may also be wired throughout the facility in various parts of the building, or may be wireless systems which are operated by security personnel. Most security alarm products are designed to have a battery backup in case of a power blackout, and some even come with smoke detectors, which are useful for detecting fires that may start in places that are not always well-lit. There are several types of security alarm systems, including the basic burglar alarm, motion detection alarm, thermal alarm, and many more.
A basic burglar alarm system works by detecting any noise that is detected within its range. The frequency of the signal is set by the manufacturer, and varies according to the equipment. If the equipment operates in a closed space, it is called a line of sight security alarm. For homes and offices which are equipped with closed-circuit TV cameras, the equipment is often referred to as a PIR (passive infrared) camera. For an even smaller home alarm system, there are wireless home security sensors. These sensors are usually used to detect motion or body heat signatures within a certain radius of the sensors.
Some wireless home alarm systems also have what are called PIR pads. These pads can detect movement or body heat patterns and trigger the security alarms, but they do not function to actually apprehend burglars. Another type of security alarm in use today is the passive infrared security alarm, also known as the PIR remote control panel. These security alarms use radio waves to detect movement and, if any, make the security measures.
Some alarm systems employ what are known as signaling sensors. These are devices which detect when any unauthorized entry occurs, and send a signal to a central control unit. In some cases, these signals can be transmitted via a security alarm panel itself. These alarm panels, however, are not limited to security alarm panels.
Other security devices, such as door and window alarms and motion detectors, may also use a form of wireless technology. A door and window alarm panel may employ radio waves or microwaves to transmit the security alerts. When using a wireless security system, it is important to remember that each security device will require a dedicated connection and will therefore require a wired connection for the monitoring station monitoring the area. Thus, a security alarm panel which utilizes wireless technology may need to have a separate security alarm system wiring and monitoring station monitoring the area.
Many security companies are able to offer monitoring services of a wired nature using their existing systems. For many businesses, however, adding a security system to an existing system is often a better option. For instance, a security alarm system can help a business provide twenty-four hour security service in the event of an emergency, but it might be difficult to add monitoring to an already established system. If you are unsure whether or not your business should utilize wireless security technology, it is important to consult with a security professional. They will be able to assess your business's needs and recommend an effective security monitoring system based upon your location.
